System.Drawing.Color to System.Windows.Media.Brush

[KBou]

Hi I'm creating a Windows Forms Application with an WPF Element Host. I want to the user to set the background of an WPF element with use of a ColorDialog. So I need to convert the System.Drawing.Color to a System.Windows.Media.Brush. I got it to work when the Color is a NamedColor (isNamedColor) but else I cannot get it to work.

            System.Windows.Media.BrushConverter bc = new System.Windows.Media.BrushConverter();
            if (\_color.IsNamedColor)
            {
                ColorBrush = (System.Windows.Media.Brush)bc.ConvertFromString(\_color.Name);
            }
            else
            {
                ???????????
            }

What should I put at the ?????????

You can use Color.FromArgb to generate the appropriate values.

ColorBrush.Color.FromArgb(_color.ToArgb());

I'm doing this off the top of my head, so you may need to tweak it slightly but this should work.

Deja View - the feeling that you've seen this post before.

The System.Windows.Media.Brush ColorBrush doesn't contain anything like Color or FromArgb. Neither does the BrushConverter.

I Found It.

            System.Windows.Media.BrushConverter bc = new System.Windows.Media.BrushConverter();
            if (\_color.IsNamedColor)
            {
                ColorBrush = (System.Windows.Media.Brush)bc.ConvertFromString(\_color.Name);
            }
            else
            {
                ColorBrush = (System.Windows.Media.Brush)bc.ConvertFromString("#"+\_color.Name);
            }

When it is not a NamedColor it returns for example ffffff80. When you add a # it recognizes and converts it. Thanks Anyway

Colours and Brushes are two different things. As mentioned above you can access the components of the colour individually to swap between a System.Drawing and a WPF color.

using (System.Windows.Forms.ColorDialog d = new System.Windows.Forms.ColorDialog())
{
d.ShowDialog();
System.Drawing.Color c = d.Color;
Background = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(c.A,c.R,c.G,c.B));
}

System.Drawing.Color c1 = new System.Drawing.Color();
        c1 = System.Drawing.Color.FromName(mycolorString);
        System.Windows.Media.Color c2 = new Color();
        c2 = Color.FromArgb(c1.A, c1.R, c1.G, c1.B);
